Title: Process for obtaining hmg-coa reductase inhibitors of high purity
Inventor: GRAHEK ROK
IPC: C07D207/34
Filed: 1999-09-17
Abstract: Lovastatin, pravastatin, simvastatin, mevastatin, atorvastatin, and derivatives and analogs thereof are known as HMG-CoA reductase inhibitors and are used as antihypercholesterolemic agents. The majority of them are produced by fermentation using microorganisms of different species identified as species belonging to i(Aspergillus), i(Monascus), i(Nocardia), i(Amycolatopsis), i(Mucor) or i(Penicillium genus), some are obtained by treating the fermentation products using the method of chemical synthesis or they are the products of total chemical synthesis. The purity of the active ingredient is an important factor for manufacturing the safe and effective pharmaceutical, especially if the pharmaceutical product must be taken on a longer term basis in the treatment or prevention of high plasma cholesterol. The accumulation of the impurities from the pharmaceuticals of lower purity may cause many side effects during the medical treatment. The present invention relates to a new industrial process for the isolation of HMG-CoA reductase inhibitors using so- called displacement chromatography. Use of the invention enables to obtain HMG-CoA reductase inhibitors of high purity, with high yields, lower production costs and suitable ecological balance.

Abstract: Abstract This invention relates to a procedure for the fabrication of an article including a film comprising at least one oxidized iron compound on a substrate.  The substrate is wetted by a solution of a polymerized product in a suitable solvent removable by volitalization at a temperature below 250°C  the polymerized product comprising an addition polymer having a molecular weight of at least 3000 Mv of a monomer. The monomer consists of two five-membered carbonaceous rings containing a .pi.-bonded iron atom.  The rings include as a substituent a mono-olefinic hydrocarbon side chain, any further substituents being saturated.  The solvent is removed leaving a continuous layer of the dried polymer product and then the layer is oxidized in an oxygen-containing atomosphere at a temperature of at least 250°C so as to convert the dried polymer into a film containing an oxide of iron.  This technique avoids many of the problems of the chemical vapor deposition technique, such as the release of carcinogenic material into the atmosphere.

Abstract: ABSTRACT OF THE DISCLOSURE Highly unusual and useful novel high-performance, oriented, low-crystalline, essentially heterocyclic structures, e.g. films, are prepared from certain novel and important process sequences.  These structures, e.g. films (in the direction of orientation) and fibers, possess a unique combination of minimal shrinkage at high temperatures, after orientation, coupled with negli-gible coefficient of expansion over an unusually wide temperature range.  These advantages are obtained in an orientation process by controlling and selecting; (a) the temperature of orientation or stretching; (b) the rate of orientation; (c) the ultimate percent of stretch in the final product; and (d) a relatively rapid quench.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus are provided for descaling hot rolled steel strips or sheets by abrasion.  This is preferably accomplished with an abrasive roll, which comprises a hub having a multiplicity of abrasive sheets extending generally radially therefrom and rotated at high speed with outer edges in contact with the metal strip moving thereby.  The abrasive roll can have a length less than the width of the strip with means provided for maintaining one end of the abrasive roll in alignment with one longitudinal edge of the strip.  This improves the life of the abrasive sheets since they do not move transversely over the longitudinal edge of the strip.  The steel strip also can be supported in a curved manner to present a convex surface toward the abrasive roll when in contact therewith.  The bent configu-ration of the strip help  to loosen the scale and hastens the descaling operation.  For a lower production and lower cost descaling operation, one abrasive roll can be used with the steel strip coiled and uncoiled in a manner to present opposite surfaces toward the abrasive roll when it is moved thereby in two passes.  To further improve the life of the abrasive roll, it is periodically checked to determine its condition of balance.          Weights can then be added to the hub to restore the balanced condition, as necessary.  A back-up roll for supporting a steel strip in contact with the abrasive roll can have metal collars supporting edge portions of the strip to prevent undue wear of the back-up roll.

Abstract: ABSTRACT OF THE DISCLOSURE In last line velocity compensation of color television signals reproduced by video recorders, the velocity error signal for the next to last line of information before the head switch that occurs during the vertical blanking interval is stored for a time extending beyond the period of the last line.  The switching between transducers that occurs during each vertical blanking interval is delayed so that a color burst signal following the last line is reproduced and a velocity error for the last line generated.  This last line velocity error signal is differentially compared with the stored next to last line velocity error to provide a velocity error difference signal.  The error difference signal is stored for the period between the foregoing and succeeding vertical blanking intervals.  The stored velocity error difference signal is added to the velocity error of each of the next to last lines of video information reproduced before switching between transducers at times between such vertical blanking intervals to provide last line velocity error compensation for those intervening last line.

Abstract: ABSTRACT OF THE DISCLOSURE        The disclosure of this application is directed to silver catalyzed manganese dioxide which is useful as a hydrogen gas absorber.  The silver catalyzed manganese dioxide of this invention can be formed into a shaped article of desired configuration, inserted into an electrochemical cell such as a battery, which is subsequently sealed, to absorb hydrogen gas evolved within the cell.  Absorption of hydrogen gas by the silver catalyzed manganese dioxide prevents excessive build-up of gas pressure within the sealed cell thus minimizing the possibility of rupture and complete failure of the cell.
